The '''TIP120 Series''' Collector is connected to the positive ''(+ve)'' supply via the load. NB If the load is inductive i.e. has coil windings such as a relay, solenoid or motor, then it is usual to connect a diode across it to prevent the Back EMF from damaging the transistor. ''(Cathode to supply)''. The input is connected to the Base via a limiting resistor ''(typically 1K)''. The Emitter is connected to the negative ''(-ve)'' supply ''(0V)''.


'''Uses:''' As current amplifiers, audio amplifiers and electronic switches, for example, Motor Drive Amplifiers, Relay Drive Amplifiers.


'''Data:''' The TIP 120 series transistors are Darlington Pairs i.e. they have 2 transistors in the one package, which gives them the advantage of higher power handling and gain.
* Voltage between Collector and Emitter 6 - 60 Volts max.
* Power handling capacity 60 Watts max.
* Current handling capacity 5 Amps max.
* Amplification (gain) greater than 1000.
